The May Measurement Month (MMM) campaign was conducted in Vietnam in 2023 to raise awareness of raised blood pressure (BP). Adults aged ≥18 years were recruited through convenience sampling at multiple sites across various provinces and cities throughout Vietnam. Three seated BP readings were taken from each participant, and a questionnaire collected information on demographics, lifestyle factors, and comorbidities. Hypertension was defined as a systolic BP ≥140mmHg or diastolic BP ≥90mmHg or being on BP-lowering medication. Controlled BP was defined as being on BP-lowering medication with a BP <140/90mmHg. Multiple imputation was used to estimate missing BP readings. In total, 10,944 adults were screened, with a mean age of 53.5 years and 52.3% were female. Of all participants, 4,905 (44.8%) had hypertension, of whom 3,673 (74.9%) were aware, and 3,584 (73.1%) were on antihypertensive medication. Of those on antihypertensive medication, 1,925 (53.7%) had controlled BP, and of all participants with hypertension, 39.2% had controlled BP. The MMM campaign in Vietnam identified a substantial number of participants with untreated or inadequately treated hypertension. These findings underscore the urgent need for strengthened national strategies to improve hypertension screening, treatment accessibility, and long-term blood pressure control.
